SPlNDLE-BEARING.

SPECIFICATION forming part of Letters Patent No. 669,655, dated March12, 1901.

Application filed. November 15, 1900.

To aZZ whom, it may concern:

Be it known that I, JACOB M. OLINGER, a citizen of the United States,residing at Vienna Crossroads, in the county of Clark and State of Ohio,have invented certain new and useful Improvements in Spindle-Bearings,of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to spindle-bearings for disks employed asfurrow-openers for grain-drills and for other purposes and forwheel-bearings in general, and has for its object to provide means forefficiently lubricating the bearing with the consumption of arelativelysmall amount of lubricating material.

To this end the invention consists in certain novel features, which Iwill now proceed to describe and will then particularly point out in theclaims.

In the accompanying drawings, Figure 1 is a side elevation of a diskhaving my improved bearing applied thereto. Fig. 2 is an edge View ofthe same. Fig. 3 is a view of one end of the bearing. Fig. 4 is a viewof the other end thereof. Fig. 5 is side elevation of the bearing. Fig.6 is a sectional View taken on the line 6 6 of Fig. 4. Fig. 7 is asectional view taken on the line 7 7 of Fig. 6. Fig. 8 is a detail planview of the spindle detached. Fig. 9 is a sectional view taken on theline 9 9 of Fig. 8. Fig. 10 is a View illustrating one way of mountingthe device. Fig. 11 is a view illustrating the device as applied to thebearing of a vehicle-wheel. Fig. 12 is a sectional view similar to Fig.7, illustrating amodification. Fig. 13 is a sectional view taken on theline 13 13 of Fig. 12. Fig. 14 is a plan view of the modified form-ofspindle detached. Fig. 15 is an inverted plan view of the same; and Fig.16 is a sectionalview of the same, taken on the line 16 16 of Fig. 14.

In the said drawings Ihave shown in Figs. 1 to 9, inclusive, aconstruction embodying my invention in its preferred form. In thisconstruction 1 indicates the disk, which is preferably of theusualconcavo-convex form, and 2 the hub thereoflprovided with the usualSerial No. 36,556. (No model.)

radial flange 3, by means of which the disk proper and the hub aresecured together by riveting or otherwise. The body portion 4 of the hubis hollow and cylindrical in form and is adapted to receive and fit upona bearing sleeve or spindle 5 on which it rests. The spindle 5 isprovided at one end with a head 6, preferably of about the same diameteras the body 4 of the hub, and in the same end of said spindle is formeda square or polygonal aperture 7. The other end of the spindle isprovided with an aperture 8. The interior of the spindle 5 is hollow,forming a chamber or recess 9. A. slot or opening 10 extends from saidchamber or recess to the top of the spindle, and a second slot oropening 11 extends from said recess or chamber to the bottom of saidspindle. The outer surface of the spindle is cut away for some littledistance back of the rear edge of the mouth of the slot 10, as indicatedat 12, while the opposite or front edge 13 extends to a contact with theinner surface of the hub and acts to some extent as ascraper. There isprovided in the body of the hub an oil-inlet aperture 14, closed by ascrew 15 or other suitable closure. The interior chamber 9 of thespindle is provided with a lining or body of felt 16 or other suitablefibrous material, having a downwardly-extending portion 17, which fitswithin the slot 11 and extends to the bearing-surfaces of the spindleand hub. The body of felt has a central aperture for the passage of theretaining-bolt hereinafter described, and its upper edges abut againstshoulders 18, formed in the upper part of the chamber and serving tohold the felt in position and prevent slipping.

A washer 19 fits within the outer end of the hub 2 and has an annularextension or collar 20 extending into the aperture 8 of the spindle andis further provided with an aperture 21 for the passage of theretaining-bolt. A packing 22, of leather or other suitable material, isinterposed between the meeting faces of the spindle and Washer toprevent escape of the oil or other lubricant. The washer projectsslightly beyond the hub to prevent binding of this latter when the partsare assembled.

The bearing may be supported in any suitable manneras, forinstance, inthe manner shown in Fig. 10, in which the bearing-spindle and its washerare clamped between the drag-bars 23 by means of a bolt 24, passingthrough the bars and bearing, having a squared or polygonal portion 25to fit the aperture 7 and prevent the spindle from turning, and providedwith a nut 26.

The bearing thus constructed operates in the following manner: Thelubricant is introduced by removing the screw 15 and turning the disk soas to cause the aperture 14 to register with the groove 10, the screwbeing replaced after the proper amount of oil has been poured in. Theoil passes down into the chamber 9 and through the felt l6 and itsextension 17 to the bearing-surfaces by way of the slot 11. The feltretards the flow and prevents the delivery of the oil in excessivequantities. The oil is carried up by the rotation of the disk and againdelivered to the chamber of the spindle by way of the slot 10, so thatthe oil is used over and over again. This gathering in of the oil isfacilitated by reason of the cutting away of the spindle at one side ofthe mouth of the inlet-slot, since the disk when at work revolves in thedirection of the arrow in Fig. '7, so that the oil carried up by therotating hub is to a considerable extent deposited in this cut-awayportion and flows thence into the slot. The scraping edge 13 also aidsin directing the oil into the slot in an obvious manner. I have found bypractical experience that a bearing constructed in accordance with myinvention will remain properly lubricated when supplied with a givenamount of oil for a much longer period than the bearings now in commonuse.

The details of the invention may obviously be varied without departingfrom the principle of my invention, and as an illustration of this Ihave shown in Figs. 12 to 16, inclusive, a modified construction inwhich instead of the slot 10 I employ a groove 27, communicating withthe inner chamber of the spindle by apertures 28. In this constructionthe cut-away portion 12 is dispensed with, as are also the shoulders 18.The structure is also adapted for use as a bearing for general use inconnection with vehicle and other wheels, and in Fig. 11 I have shownsuch a construction, which Will be readily understood in connection withthe preceding description without further detailed explanation.

Other modifications will readily suggest themselves, and I therefore donot Wish to be understood as limiting myself to the precise detailshereinbefore described, and shown in the drawings.

Having thus fully described my invention, whatI claim as new, and desireto secure by Letters Patent, is
